What is S35VN Steel? A Complete Guide for Knife Users

If you’ve been looking into premium folding knives, chances are you’ve come across the term S35VN steel. It’s one of the most respected blade steels in the EDC (Everyday Carry) and tactical knife world—but what exactly makes it special?

This guide breaks down everything you need to know about S35VN steel, from its composition and performance to why it is widely used in high-end folding knives.

What Is S35VN Steel?

S35VN (CPM S35VN) is a powdered stainless steel developed by Crucible Industries. It is an upgraded version of S30V steel, designed to improve toughness and ease of sharpening while maintaining excellent edge retention.

In simple terms, S35VN is a high-end knife steel engineered to balance durability, sharpness, and corrosion resistance.

S35VN Steel Composition

S35VN is produced using the CPM (Crucible Particle Metallurgy) process, which creates a finer and more uniform grain structure compared to traditional steels.

Key elements include:

• Carbon (C): improves hardness and edge retention
• Chromium (Cr): enhances corrosion resistance
• Vanadium (V): increases wear resistance
• Niobium (Nb): improves toughness and sharpening performance

The addition of niobium is what makes S35VN a significant upgrade over S30V.

Key Performance Features of S35VN

Excellent Edge Retention

S35VN maintains sharpness for extended use, making it ideal for daily EDC tasks.

Balanced Toughness

It resists chipping better than ultra-hard steels, offering reliable performance in real-world conditions.

Strong Corrosion Resistance

With high chromium content, S35VN performs well in humid and outdoor environments.

Easier Maintenance

Compared to S30V, S35VN is easier to sharpen while still maintaining premium-level performance.

S35VN vs Other Knife Steels

S35VN vs D2 Steel

S35VN is stainless and requires less maintenance, while D2 offers higher hardness but is more prone to rust.

👉 If you want low-maintenance performance, S35VN is the better choice.

S35VN vs S30V

S35VN improves toughness and sharpening ease, while S30V offers slightly higher edge retention but is more brittle.

👉 S35VN provides better real-world balance.

S35VN vs Budget Steels

S35VN sits in a completely higher performance tier compared to entry-level steels such as 8Cr13MoV.

Why Knife Makers Prefer S35VN

S35VN is widely used in premium folding knives because it provides:

• Consistent manufacturing performance
• Excellent balance of properties
• Strong positioning in the premium market

For brands, it represents reliability and quality. For users, it means long-term performance.

Is S35VN Good for EDC Knives?

Yes. S35VN is one of the most reliable steels for everyday carry knives.

It performs well in:

• Daily cutting tasks
• Outdoor use
• Work environments
• Tactical situations

It is especially suitable for users who want a “set and forget” performance steel.

Who Should Choose S35VN?

S35VN is ideal for:

• EDC users who want long-term reliability
• Outdoor and field professionals
